Back in 2011 when the Viper ACR gained the production car lap record with a time of 7:12.13, the track version the ACR-X was doing some hot laps.

At the time we was spending some time with the guys from the Viper Club of America and showing them around some of the many good photo spots on the Nordschleife, they hinted at the time the ACR-X achieved but thought id hold on until the video surfaced.

Well here it is the SRT ACR-X Managed to lap the ring in an impressive 7:03.05

The ACR-X is powered by a 8.4-liter V10, with revised headwork and free flowing exhaust it gains around 40hp more than the standard model.
